SLOPE OPERATION
WARNING
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
Operation on all slopes requires extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not operate
on it.
Control of a walk-behind or ride-on machine sliding on a
slope will not be regained by the application of the brake.
The main reasons for loss of control are: insufficient tire
grip on the ground, speed too fast, inadequate braking, the
type of machine is unsuitable for its task, lack of awareness
of the ground conditions, incorrect hitching and load distribution.
1. Mow across slopes, not up and down.
2. Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to stop
or change speeds while on the slope.
4. Do not mow on wet grass. Tires may loose traction.
5. Never mow down slopes.
6. Avoid starting, stopping, or turning on a slope. If tires
lose traction (i.e. machine stops forward motion on a
slope), disengage the blade(s) (PTO) and drive slow
off the slope.
7. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction,
which could cause the machine to rollover.
8. Use extra care while operating machines with grass
catchers or other attachments; they can affect the
stability of the unit. Do not use on steeps slopes.
9. Do not try to stabilize the machine by putting your
foot on the ground (ride-on units).
10. Do not mow near drop-offs, ditches, or embankments. The mower could suddenly turn over if a
wheel is over the edge of a cliff or ditch, or if an edge
caves in.
11. Do not use grass catchers on steep slopes.
12. Do not mow slopes if you cannot back up them.
13. See your authorized dealer/retailer for recommendations of wheel weights or counterweights to improve
stability.
14. Remove obstacles such as rocks, tree limbs, etc.
15. Use slow speed. Tires may lose traction on slopes
even through the brakes are functioning properly.
16. Do not turn on slopes unless necessary, and then,
turn slowly and gradually uphill, if possible. Never
mow down slopes.
Never operate on slopes greater than 17.6 percent
(10°) which is a rise of 3-1/2 feet (106 cm) vertically in
20 feet (607 cm) horizontally.
Select slow ground speed before driving onto slope.
Use extra caution when operating on slopes with rearmounted grass catchers.
Mow across the face of slopes, not up and down,use
caution when changing directions and DO NOT
START OR STOP ON SLOPE.
CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will
remain where you last saw them.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and
down for small children.
4. Never carry children, even with the blade(s) off. They
may fall off and be seriously injured or interfere with
safe unit operation. Children who have been given
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over
by the machine.
5. Never allow children to operate the unit.
6. Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
EMISSIONS
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
TOWED EQUIPMENT (RIDE-ON UNITS)
IGNITION SYSTEM
1. Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
2. Follow the manufacturer’s recommendations for
weight limit for towed equipment and towing on
slopes. See attaching a trailer under OPERATION.
3. Never allow children or others in or on towed equipment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast down hill.
1. This spark ignition system complies with Canadian
ICES-002.

CONTROL FUNCTIONS
The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing
require the combined use of several controls applied in specific sequences. To learn what combination and sequence
of controls to use for various tasks please read the entire section.
Throttle Control
Ground Speed Levers /
Parking Brake
The throttle controls engine speed. Always operate at
FULL throttle when mowing. Move the lever forward to
the detent for FULL throttle (FAST). Move the throttle
back to decrease engine speed to IDLE (SLOW).
These levers control the ground speed and parking brake
of the rider. The left lever controls the left rear drive
wheel and the right lever controls the right rear drive
wheel and parking brake.
Choke
Pushing the levers out, away from the operator’s lap
locks the parking brake in PARK position (inset, Figure
1). Pulling the levers in across the operator’s lap puts the
levers in DRIVE positions.
Close the choke for cold starting. Open the choke once
the engine starts. A warm engine may not require choking. Move the lever forward to close the choke. Move the
lever back to open the choke.
From DRIVE position, moving a lever forward increases
the FORWARD speed of the associated wheel. Pulling
back on a lever increases the REVERSE speed. The further a lever is pushed, the faster the drive wheel will turn.
See DRIVING PRACTICE for steering instructions.

DRIVING PRACTICE -
Smooth Travel
BASIC DRIVING
The lever controls of the
zero turn rider are
highly responsive.
WARNING: Never operate on slopes greater than 17.6%
(10°). See SLOPE OPERATION in the safety section.
Zero turn riders operate differently from other fourwheeled vehicles. The drive wheels are also your steering wheels. If you cannot drive the unit on a hill, you will
not be able to steer the unit on it. Operating zero turn
units on slopes requires extra caution.
The BEST method of
handling the ground
speed control levers is in
three steps — as shown
in Figure 4.
FIRST place your hands
onto the levers as
shown.
The lever controls of the zero turn rider are very responsive, and learning to gain a smooth and efficient control
of the rider’s forward, reverse, and turning movements
will take some practice.
SECOND, to go forward
gradually push the levers
forward with your palms.
Spend some time going through the following maneuvers
and becoming familiar with how the unit accelerates,
travels, and steers — before you begin mowing —is
absolutely essential to getting the most out of the zero
turn rider.
THIRD, to speed up
move the levers farther
forward. To slow down
smoothly, slowly move
the levers back toward
neutral.
Locate a smooth, flat area of your lawn — one with
plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit
at mid-throttle during this practice session (ALWAYS
operate at full throttle when mowing), and turn slowly to
prevent tire slippage and damage to your lawn.
Figure 4. Move Control
Levers Gradually
We suggest you begin with the Smooth Travel procedure
to the right, and then advance through the forward,
reverse, and turning maneuvers.
Forward Travel Practice
Gradually move both ground speed control levers evenly
FORWARD from neutral. Slow down and repeat.
Reverse Travel Practice
LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK from neutral.
Slow down and repeat.
WARNING
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns as
sharply in reverse as when going forward, and backing
up straight takes practice.
Do not mow in reverse unless absolutely
necessary. Always look down and behind before
and while travelling in reverse.
Reverse Travel
Forward Travel
Figure 5. Forward Travel
Figure 6. Reverse Travel
12
Practice Turning Around a Corner
Practice Turning In Place
While traveling forward allow one handle to gradually
return back toward neutral. Practice several times before
mowing.
To “zero turn” means to turn in place. To turn in place,
gradually move one ground speed control lever forward
from neutral and one lever back from neutral simultaneously. Repeat several times.
NOTE: To prevent damaging your lawn by pivoting directly on the tire tread, it is best to keep both wheels going at
least slightly forward.
Turning In Place
Executing Turns
Figure 7. Right Turn
Figure 8. Turning in Place
ADVANCED DRIVING
Executing an End-Of-Row Zero
Turn
Your zero turn rider’s unique ability to turn in
place allows you to turn around at the end of
a cutting row rather than having to stop and
make a Y-turn before starting a new row.
For example, to execute a right end-of row
zero turn:
1. Slow down at the end of the row.
2. Move the LEFT ground speed control
lever forward slightly while moving the
RIGHT ground speed control lever back to
center and then slightly back from center.
3. Begin mowing forward again.
This technique turns the rider RIGHT and
slightly overlaps the row just cut —eliminating
the need to back up and re-cut missed grass.
As you become more familiar and experienced with operating the zero turn rider, you
will learn more maneuvers that will make your
mowing time easier and more enjoyable.
Remember, the more you practice, the better your control of the rider will be!

STORAGE
STORAGE
WARNING
Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety
Rules section, then perform the following steps:
Never store the unit (with fuel) in an enclosed,
poorly ventilated structure. Fuel vapors can
travel to an ignition source (such as a furnace,
water heater, etc.) and cause an explosion.
• Disengage the PTO, set the ground speed control
levers to PARK, & remove the key.
Fuel vapor is also toxic to humans and animals.
• Check all fluid levels. Check all maintenance items.
• Battery life will be increased if it is removed, put in a
cool, dry place and fully charged about once a
month. If the battery is left in the unit, disconnect the
negative cable.
A
It is important to prevent gum deposits from forming in
the essential fuel system parts such as the carburetor,
fuel filter, fuel line, and fuel tank during storage. Also,
alcohol blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to the separation and formation of acids during storage. Acidic gas
can damage the fuel system of an engine while in storage.
To avoid engine problems use fuel stabilizer, especially
before storage of 30 days or longer.
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Fill with FRESH fuel.
• After starting, allow the engine to warm before operating.

WARNING
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is still hot from recent operation. Do not
allow open flame, smoking or matches in the area.
Avoid over-filling and wipe up any spills.

TROUBLESHOOTING
While normal care and regular maintenance will extend the life
of your equipment, prolonged or constant use may eventually
require that service be performed to allow it to continue operating properly. The troubleshooting guide below lists the most
common problems, their causes and remedies.
WARNING
To avoid serious injury, perform maintenance on
the rider or mower only when the engine is
stopped and the ground speed levers are set to
PARK.
Always remove the ignition key, disconnect the
spark plug wire and fasten it away from the plug
before beginning the maintenance, to prevent
accidental starting of the engine.
If you prefer, all of these procedures can be performed for you
by an authorized dealer.

Specifications
NOTE: Specifications are correct at time of printing and are subject to change without notice.
* The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002–05). Given both the wide
array of products on which our engines are placed, and the variety of environmental issues applicable to operating the
equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a piece
of power equipment (actual “on–site” power). This difference is due to a variety of factors including, but not limited to,
the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, maximum
governed engine speed, individual engine to engine variability, design of the particular piece of power equipment, the
manner in which the engine is operated, engine run–in to reduce friction and clean out of combustion chambers,
adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match the values
derived using the foregoing codes.
